IGS is a file format specified by the U.S. Information Management Council. It is a file generated according to the IGES standard and is mainly used for file conversion of different 3D software systems. Files in IGS format can be opened by 3D modeling software such as UG, SolidWork, CATIA, and Pro-E, but they cannot be edited or modified. The main problems exposed in the application of IGS files are: the data file is too large and the data conversion processing time is too long; only paying attention to the conversion of graphic data and ignoring the conversion of other information.

IGS is a file generated according to the IGES standard and is mainly used for file conversion in different 3D software systems.
Files in this format can be opened by 3D modeling software such as UG, SolidWork, CATIA, Pro-E, etc., but cannot be edited or modified.
The file in this format is a file format generated according to the IGES standard. IGES is the de facto international standard data exchange format widely used in various countries. my country has adopted IGES3.0 as a national recommended standard since September 1993. The standard is built on Boeing's CAD/CAM Integrated Information Network, General Electric's central database and various other data exchange formats.
The main problems exposed by IGS files in applications are: the data file is too large and the data conversion processing time is too long; only paying attention to the graphics data conversion and ignoring other information Convert.
Other graphic file standards for three-dimensional data exchange include the DXF (DataExchangeFile) file of the AutoCAD system, the international standard STEP (Standard for the Exchange of Product modeldata), etc.
Extended knowledge:
The graphics file standards used for data exchange on microcomputers and workstations mainly include: DXF ( DataExchangeFile) file, the American standard IGES (Initial Graphics Exchange Specification, that is, the initial graphics exchange specification) and the international standard STEP (Standard for the Exchange of Product modeldata). Some other more important standards include: the CAD-I standard funded by ESPRIT (European Strategic Plan for Research and Development of Information Technology) (limited to finite element and shape data information); Germany's VDA-FS standard (mainly used in automobiles) Industry); France's SET standard (mainly used in the aerospace industry), etc.
The IGES standard is based on Boeing's CAD/CAM Integrated Information Network, General Electric's central database and various other data exchange formats. Its initial version was limited to describing the geometry and annotations of engineering drawings, later incorporating electrical, finite element, plant design, and architectural design. IGES4.0, announced in June 1988, absorbed the CSG (Constructive Solid Geometry, meaning voxel construction method) and assembly model in ESP, and later expanded to include new graphic representation methods, three-dimensional pipeline models and FEM (Finite Element Model) functionality improvements. The B-rep (boundary representation) model is defined in IGES5.0. However, IGES unreasonably defines a direct access pointer system in the file structure.
